Definitions

  • US-A-5 141042 describes a vertical blind vane consisting of a PVC insert which is covered by a fabric sleeve.
  • DE-A-3207850 describes a flat fabric vertical blind vane.
  • FIGURE 6A is a section taken along line 6A-6A of Fig. 6.
  • FIGURE 6C is a section taken along line 6C-6C of Fig. 6.
  • FIGURE 6D is a section taken along line 6D-6D of Fig. 6.
  • FIGURE 32 is a fragmentary isometric similar to Fig. 31 showing an alternative system for reinforcing the top end of a vane.
  • the window blind 30 is operative for movement between extended and retracted positions, as well as open and closed positions.
  • the vanes In the extended position shown in Fig. 1, the vanes are uniformly distributed across the window opening, while in the retracted position (not shown), the vanes are horizontally stacked together adjacent either or both sides of the window opening.
  • the vanes are pivotal to move the blind between the open and closed positions.
  • the vanes In the open position shown in Fig. 1, the vanes extend perpendicularly to the headrail, while in the closed position of Figs. 3 and 5, they preferably partially overlap in shingle-like touching relation and extend in substantially parallel relation to the headrail.
  • the fabric straightener takes any inherent bow, or curve, out of the raw fabric before it is further processed.
  • the fabric straightener 57 is desirable because the tubular vane construction can amplify any curve present in the raw fabric into a significant bow in the finished vane. For example, if a roll of 7-inch wide vane material is rolled and laid flat on the floor over a length of 12.7 metres (50 feet), the material may bow as much as 6.35 mm (1/4 inch) over the 12.7 metre (50-foot) length. When this bowed material is produced into a vane, the vane might also have 6.35 mm (1/4 inch) or more of bow in a 1.82 metre (six foot) length. This amount of bow is typically unacceptable in the window covering industry where aesthetics are of prime importance. In fact, any bow greater than about 6.35 mm (1/4 inch) in a vane that is 2.13 metres (84 inches) long or less is generally unacceptable.
  • the first test compared a single-ply and double-ply planar prior art type vane to a tubular vane made in accordance with Fig. 7 of the present invention wherein the vanes were all made from a 100 gram/m 2 acrylic bonded polyester spun bond nonwoven fabric manufactured by Unitika Corporation of Japan.
  • the test results are shown in Fig. 26.
  • the amount of force required to twist the lower edge of the vanes through the designated number of degrees is recorded in the three tables of Fig. 26. It will there be seen that the force required to rotate a non-tubular, single-ply fabric vane through 45 degrees, for example, is approximately 1.5 grams.
  • the force required to rotate a non-tubular, 2-ply fabric vane through 45 degrees is slightly more than 1.5 grams.
  • a guide rail 298 having a groove 300 in an upper surface thereof is provided at the outlet end of the apparatus shown diagrammatically in Fig. 6 to guide a preformed and cut vane 290 to the end forming apparatus.
  • a die set 302 is positioned immediately adjacent the end of the guide rail 298 for cutting the end of the vane into a predetermined configuration and a reinforcing strip inserting system 304 is aligned with the die set and guide rail for the purpose of selectively inserting a strip 306 of plastic material into the open top end of the vane.
  • the inserting system 304 includes a sword 308 having a longitudinal cavity therethrough that slidingly receive the strip 306 of plastic insert material.
  • the die set 302 is somewhat conventional in including a pair of die blocks 316 with one having a cutter head 318 with a cutting edge 320 in a predetermined form so as to cut the top end of a vane as shown in Fig. 31 in a manner to be explained later.
  • This configuration for the top end of the vane has been found to be desirable in an architectural covering of the type disclosed in WO-A-96/35854, which is of common ownership with the present application and herein incorporated by reference.
  • the die blocks 316 are simultaneously moved toward and away from each other by a somewhat conventional die set controller 322 which has a drive shaft 324 for rotating a crank arm 326 and effecting movement of push pull rods 328 connected to the crank arm at diametrically opposed locations.
